9 claims. (el. eso-152) My invention relates to improvements in antisqueak strips or webs. are used between metal parts to eliminate the squeaks and noise produced by relative movement of the parts. They are widely used in the automobile industry and particularly in automobile body construction. One specc use is between the fender and the Yadjacent body portion,

Such strips include a web portion and a mar-- ginal bead portion. The web portion is adapted to be inserted between the two adjoining metal parts. The vmetal parts are secured together through this web portion. The strip is so positioued between the metal parts that the bead portion extends along and overliesjthe joint between the metal parts. The bead has a finished outer surface so that it presents a neat finished appearance.

My invention relates to improvements in strips of this type. One objectof my invention is the provision of a strip of this nature which is inexpensive, which is moisture resistant, which is yieldingly compressible and resilient, and'which is adapted to seal the joint between the two metal parts and further to seal itself adhesively across said metal parts preventing the ingress of dirt or water into the ,joint between said parts.

A characteristic of my invention is that the web width which is disposed between the adjoining metal parts is impregnated with l'atex which forms a connective film filling the interstices of the material and extending in the form of a moisv ture resistant envelope over the outer surface of the web. In addition, it renders the web compressble and resilient and it further seals the opposed surfaces ot the web width against the adjoining mtal faces preventing the seepage of water into the joint.

Other objects, advantages, and meritorious characteristics of' my invention will more fully appear from the following specification, appended claims, and accompanying drawing, wherein:

Figure l is a vperspective of my improved welt partly unfolded to show the structure,

Fig. 2 is a cross sectional view transversely )of the welt shown in Fig. l, and

Fig. 3 is a sectional view through a fragment of a body structure showing the employment of my invention.

My improved antisqueak strip is formed of a width of webbing of suitable brous material. I prefer to employ a loosely woven brous material such as jute webbing. This material is impregnated with a suitable latex compound. The latex compound may be allowed to `set to a tacky Strips of this character condition and the strip then folded over a cord or the like, indicated as i0. This cord maybe formed of twisted paper or any other suitable material. The strip is brought together over the cord and the separate folds are pressed together.l 'I'his operation results in the formation of a double thickness of m'aterial I2 extending away from the cord in the form of a web.

Asa result of the impregnation with the latex compound and the compression of the folds together the web portion i2 is -thoroughly impregnated with the latex and the `interstices thereof are lled with such compound.

The latex extends as a lm between' the two layers of the material. It extends as a nlm over the outer surface of the web. It forms a resilient connective lm enveloping the web.

A strip of finish fabric Il, such as artificial leather or the like, is then folded over the covered cord as shown completing the formation of the bead. 'I'his finish strip is adhesively held in place thereover and upon both sides of the'web as illustrated. VThe'latex compound which was used to impregnate the web adhesively secures this strip in place. An additional layer of adhesive may be used underneath said strip if found desirable. It is unnecessary to employ any stitching or any other securing means in a construction of this character. Adhesive compound is sufllcient to secure the several parts of the finished article together. y

'I'he latex compound is utilized in a sulcient quantity so that it renders the web yieldinglyv compressible and resilient.

In the drawing the complete strip is illustrated as disposed between adjoining metal parts I6 and I8 which are held ftogether by fastening means 20. The strip completely seals the joint between such parts filling the irregularities of the opposed surfaces of the parts. In addition, it seals itself against the adjoining surfaces of themetal parts. Along and adjacent to the bead it is present' in such an amount that it forms a yielding cushion-like layer that fills the spaces between the metal parts at the entrance to the joint. Should any water seep in. however, it will not penetrate sumciently to rust the metal parts or rot the fabric material as the two surfaces of' the web portion are sealed against the opposed vr serted within relatively limited spaces between the metal parts, yet it 1s sumcientiy flexible and Y compressible to accurately conform to irregularities of the surfaces which it adjoins.

A suitable latex compound may be formed of y 50 c.c. m. of rubber latex, 4 c. c. m. of saturated solution, and 20 drops of Neoammonia and wherein pitch is dissolved to the maximum capacity of the solvent. The Neozone L (a commercial product) is an anti-oxidant and other similar suitable anti-oxidants might be used. A formula such as the above, which is a water emulsion of a rubber latex compound, is preferred. By latex or latex compound I mean a water emulsion of rubber which comprises the natural product, latex, modifications or compounds thereof, or artificial aqueous dmpersions of rubber.-

What I claim:

1. An antisqueak strip comprising a 'length of flbrous material folded upon itself `forming a double thickness web, a cord extending along one linear margin of the web, saidmaterial being impregnated with a latex compound and said two layers being compressed together with ythe latex adhesively securing them together and forming a permanently tacky moisture resisting film extending over each outer surface of the web and a film extending between the two layers constituting the web and' through the interstices of the two layers, and a finish strip folded over the foldededge of the web and adhesively secured thereto.

2. An antisqueak strip comprising a loosely woven web width so impregnated with a suitable latex compound as to form a latex coating over the individual fibers of the web material, said Width of material folded lengthwise upon itself into a double thickness web and compressed together, said latex compound adhesively securing the folds of the material together and forming a film therebetween and a film thereover and extending through the interstices of the material,va cord extending between the folds along the fold line, and a strip of hard surfaced finish material folded over the folded edge of the web and adhesively secured thereto by the outer coating of latex on the web width, said web width containing sufcient latex characterized by being normally tacky to render the same suiliciently stiff to be self-supporting while retaining yielding flexibility and resiliency.

3. An antisqueak strip comprising two superr imposed layers of loosely woven brous webbing impregnated throughout with a latex compound.

tending along one linear margin of said super-I gether.

imposed layers, said layers being compressed together and held together by the latex compound with which the layers are impregnated, said latex -compound extending between said layers and through the interstices thereof to the outer surface of each layer rendering the two layers and .the individual bers which make up the same water-resisting, and rendering said two layers sumciently rigid to be self-supporting as a unitary structure, and a strip of finishing material folded over said cord and adhesively secured to the opposite surfaces of said superimposed layers.

4. A welt comprising a bead filler, a strip of loosely woven fabric impregnated with a latex compound and folded over the' bead ller so as to provide a bead portion at one edge of the welt with a leg projecting therefrom, and a finish strip folded over said bead portion and adhesively secured thereto, said latex compound adhesively securing-said folds together.

5. A welt comprising a bead portion, superimposed layers of loosely woven fabric impregnated with and adhesively secured together by a latex compound and adhesively secured by latex compound to the bead portion so as to provide a bead along one edge of the welt with a web 'projecting therefrom, and a finish strip folded over the bead portion overlapping said layers and adhesively secured thereto.

6. An antisqueak strip for use between adjacent structural parts comprising a web of porous fibrous material impregnated with a latex compound imparting a water resistant quality to the material, a bead extending along one edge of said web and including a covering finish strip,
